Abstract

The invention discloses an indoor positioning method and an indoor positioning device, and relates to the technical field of communication. Three-dimensional displaying of indoor positioning can be realized, so that the efficiency that people read a map is improved. The method disclosed by the invention mainly comprises the following steps: after a positioned terminal starts a positioning function, positioning the positioned terminal by using an indoor positioning technology, and acquiring longitude and latitude height coordinates of the positioned terminal; acquiring a three-dimensional building model corresponding to the longitude and latitude height coordinates and coordinate conversion parameters corresponding to the three-dimensional building model; converting the longitude and latitude height coordinates into three-dimensional coordinates of the three-dimensional building model based on a preset coordinate conversion algorithm and the coordinate conversion parameters; and sending the three-dimensional building model and the three-dimensional coordinates to a preset terminal, to enable the preset terminal to display the three-dimensional coordinates in the three-dimensional building model. The indoor positioning method is mainly applicable to scenes for realizing the three-dimensional displaying of indoor positioning based on a BIM model.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to an indoor positioning method and device. Background technique [0002] The positioning technology can be mainly divided into two categories: outdoor positioning and indoor positioning. Among them, the outdoor positioning technology mainly includes satellite positioning, and the indoor positioning technology mainly includes WiFi (Wireless Fidelity, wireless fidelity) positioning, Bluetooth positioning, infrared and base station positioning. [0003] The existing positioning technologies can only display the positioning points on the map in a two-dimensional manner, that is, on the two-dimensional map, but cannot display the positioning points on the three-dimensional map. However, in practical applications, people prefer to use a three-dimensional map with a more intuitive display effect to display the positioning points. Especially for indoor positioning o...
